yes they are. i was just listing the AOE civs from the first and second game and their expansions. that's also why i only listed an idea for the Mayans, which were at the height of their power or approaching it during 0 A.D.'s timeframeand, as stated in a Q&A about the inclusion of the Aztecs and Mayans to AOK, the creators of that game clarified that they weren't savages with stone weapons and incapable of fighting off metal-using invaders (Spanish conquistadors with firearms and a few thousand native allies notwithstanding). their weapons were made of obsidian, which is many times sharper than steel when properly crafted. i even devised a basic setup of what Aztec units would be included for a separate project, reasoning that because horses were not native to their lands, they would get every infantry unit and a fast runner who is functionally a cavalryman to compensate but that's beside the point. if any Amerindian civilization were to be included, i would recommend the Mayans rather than the Aztecs or Inca. i think the only reason that the Mayans aren't as well known as the other two (and that's saying something, because the Mayans are really famous) is because their civilization had collapsed long before the Spanish arrived in Central America (ironically, they actually lasted longer than the Aztecs and Inca is resisting annexation into New Spain) true, but still, one of the ground rules about 0 A.D., iirc, is that a civilization must have been at about the height of its power between 500 BC and 500 AD in order to be included (hence dating the Romans to Caesar's time and the Spartans to Leonidas'), which is why i didn't mark down a Viking civilization in my earlier post: the Viking Age began after 500 AD, and why the Egyptians are of the Ptolemaic dynasties rather than the independent ones, because the Egyptians were not independent following 402 BC and were arguably more distinct under Greek rule than under Persian (at least, i assume)
